James Carpenter is a virtual prisoner at the US embassy in the tiny police state of Callados, convinced in absentia of espionage and sentenced to death. The only way to escape is via a bit of sleight of hand, orchestrated by John Drake with the help of Carpenter's double, who happens to be a world-class pianist.

Nicely done take on the classic "everyone has a double" idea, especially thanks to Sylvester's excellent portrayal of the two different roles. A rather ironic choice of episode titles, to be sure!
